The 3G Sunset Worldwide: How Enterprises Can Avoid Device Disruption
The era of 3G is ending. For many industrial businesses, smart infrastructure systems, remote device management, and IoT connectivity rely on networks that are now being phased out globally. The question isn’t if—but when your operations could be disrupted.
In this episode of Tech Transformed, Trisha Pillay speaks with Jana Vidis, Business Development Manager at IFB, about the worldwide 3G sunset, what it means for enterprises, and how proactive planning can prevent costly disruptions. They explore the reasons behind the transition to 4G and 5G, the impact on various industries, and the strategies organisations can implement to assess their reliance on legacy devices.
Why the 3G Sunset Matters3G networks have powered connectivity for decades, offering wide coverage and reliability. But as global operators move to 4G and 5G, maintaining 3G is no longer sustainable. Carriers are discontinuing services, and support is dwindling, leaving legacy devices vulnerable to:
- Operational downtime
- Inconsistent performance
- Increased security risks
Jana emphasises:
“Have a good understanding of what devices you have. Work with IT partners to prepare for future changes. Plan your transition and act before disruption hits.”
Jana also stressed the importance of understanding current technology deployments, planning for transitions, and future-proofing investments to avoid disruptions. The conversation highlights the need for proactive measures in adapting to technological advancements and ensuring operational continuity.
A Global TimelineThe transition is already well underway across multiple regions:
- North America: AT&T, Verizon, and T-Mobile 3G networks discontinued in February 2022; Canada’s shutdown begins in early 2025.
- Europe: Most countries, including the UK, Germany, Hungary, and Greece, will complete shutdowns by the end of 2025.
- Asia: Japan phased out 3G in 2022, Singapore in July 2024, and India plans completion by the end of 2025.
- Africa: South Africa started in July 2025; other countries are slowing the transition.
- South America: Providers like Telefonica, Entel, and Claro completed shutdowns in 2022–2023.
- Middle East: Oman started shutting down in July 2024; Zain Bahrain in Q4 2022; Kuwait, Iran, and Jordan are following.
Industrial devices still using 3G must transition now to avoid operational disruption. From smart infrastructure to remote IoT systems, legacy devices left unaddressed can cause downtime, inconsistent performance, and increased security risks.
Takeaways- 3G networks are being phased out to enable 4G and 5G development.
- Businesses must assess their reliance on 3G devices before shutdowns.
- Legacy devices can cause operational disruptions if not addressed.
- Understanding current technology deployments is crucial for businesses.
- Proactive planning can mitigate risks associated with network changes.
- Investing in infrastructure now can save costs in the future.
- Collaboration with IT partners is essential for smooth transitions.
- Testing new devices before rollout is a best practice.
- The demand for faster connectivity is driving technological advancements.
- Future-proofing technology investments is key to long-term success.
